I'll openly admit to not being an expert on how to implement things like these. If it's possible to be stored on steemit.com, I'm not sure I see a reason for them to be stored on the blockchain.
What I mean by this is to simply have clickable shortcuts that the user can choose. From, say, three to five. So, I'd have "gaming" clickable on the upperhand bar next to "active", and it would be a shortcut to "steemit.com/created/gaming".
I am, or used to be, an expert on implementing things.
The only thing I don't know is how much stuff is stored on steemit.com, and how much its database is being taxed right now. I tried to find out in chat, but the conversation never even starts.
What I really do not know is people's expectations. I have been living under a rock for a few years. So, I really need to have the above questions answered.
And, I believe I wrote somewhere on this chain, about a much more structured and useful tagging system. It again, was just dropped.
Simply being able to Follow Tags would work, too.
